Construction and Implementation Services

1 – Project Initiation and Blueprint Preparation

Preparing the blueprint is the first step in the construction process. The building blueprint displays various details such as area, built-up space, rooms, the permitted number of floors, the type of usage, and more. To prepare the building blueprint, the first step is to submit the land documents to the municipality for their verification and to obtain a blueprint preparation order. Once your blueprint is designed, it must be sent back to the municipality for final approval. After final approval, a construction permit, which serves as the building’s identity document, is issued for you.

2 – Excavation

Excavation for constructing the building’s foundation or footing marks the start of the actual construction operations. The depth of excavation is determined based on the number of floors and the load that will be imposed on the foundation. This task must be carried out with utmost precision and by a structural engineer, as any miscalculation in excavation can pose significant risks to the building and its occupants.

3 – Concreting and Rebar Work

At this stage, the pit must be filled with a 10 to 15 cm layer of concrete. This concrete bears the load from the structure and prevents the building from settling. Afterwards, the building’s footing is reinforced with mesh rebar. Given the use of rebar in the footing, the price of rebar (16mm, 14mm, or other sizes commonly used in foundations) significantly impacts the total cost of this phase.

4 – Formwork and Concreting

In this phase, the area to be concreted must be formed using polymer, metal, or wooden formwork. Using plastic formwork such as Arka eliminates the need for oiling and prevents concrete from sticking to the forms. Furthermore, execution speed increases significantly with the use of these forms. Proper execution of this stage greatly contributes to the building’s strength; therefore, it is best carried out by specialists with the highest level of precision.

5 – Selection and Implementation of the Main Building Frame

Buildings can be constructed with either a steel or concrete frame. If structural strength is a higher priority for you, a steel frame is undoubtedly preferable. Of course, each of these two options has its own specific advantages and disadvantages. Therefore, you must evaluate the conditions according to the structural design. Concrete frames are more economical for builders, as the price of the beams used in a steel structure is significantly higher than that of concrete.

6 – Wall Construction

Wall construction can be done in various ways. One method is the use of prefabricated walls. Prefabricated walls are more economical, offer greater strength, and also provide better sound and thermal insulation properties compared to brick.

7 – Installation of Utilities

After completing the wall construction in the building stages, it is time for the installation of utilities. Installing utilities includes steps such as gas piping, water piping, electrical network installation, and more. Each of these items requires its own specific expertise and skill and must be performed by professional personnel, as most of these utilities are installed in internal sections such as false ceilings or floor structures. If not executed correctly, they can cause many problems in the future.

8 – Wall Covering and Plastering

Plastering, or whitewashing, involves smoothing plaster onto the walls and then thoroughly floating it to ensure no issues arise during painting.

9 – Floor Screeding, Waterproofing, and Floor Covering with Mortar

At this stage, the building floor must be covered with a layer of mortar. After drying, the house floor is covered with mosaic, tile, or any other material and waterproofed to ensure its durability.

10 – Wall Tiling

Wall tiling is done using a plumb line. After the tiling is completely dry, the joints must be grouted with white cement.

11 – Ceiling Finishing

For this task, either a false ceiling can be used, or the ceiling can be finished from the inside using plasterwork. Plasterwork was commonly done in the past and is a traditional method. After this stage is completed, the building facade is executed as the final stage of construction. Following site cleanup, the building is ready to be handed over to the owner.

12 – Installation of Doors, Windows, and Faucets

Finally, after completing all the above stages, it is time to install windows, doors, faucets, etc., which must be done according to national regulations. At this stage, adhering to safety points and Iran’s national regulations is very important.
